Hi Now here the thing, i have strange noise comming form the drivers side of the car, like a ticking/squeeking sound but its only sometimes and only when the car is excellerating until it hits 3000rpm, then it stops and will return about half an hour later. It has to be in drive and the car moving for me to here the sound, i have tried parked up and reved it but it just disappears and cannot find the source. Has anybody got any thoughts on this or had the same problems. It becoming really anoying now but i am not loosing any power etc and it runs fine.

I had the bonnet open today reving it to find the noise and i had smoke appearing from the near the manifold at the bottom of the heat shield when i reved it. i will look at this later does anybody think they are related, maybe cracked manifold? but why the sound?
cheers

I dont know if those two are related, but I had a squeaking chirping noise like you described that turned out to be the instrument binnacle rubbing on the trim due to engine/driving vibration. Hopefully its somthing easy like that for you.

Had a similar symptom, luckily turned out to be just the gasket between the manifold and downpipe blowing slightly.

Really simple job to do, a ratchet, couple of extentions and a 14mm or 9/16" socket if I remember right. Done from underneath I actually did both sides and fitted new studs and nuts while I was at it.

Cheers

Hi All checked today no leak from mnaifold joint must be higher up, anybody got any other thoughts before i take it in to the indy. Would a cracked manifold give me the problems i have described i am unsure. I thought the blow would be constant not just under load.

I removed my right hand manifold shroud to find the flex joint cracked and leaking. It went away as the engine warmed up. I tried exhaust sealer and bandage but due to the flex it failed so tried high temp silicone gasket maker which is holding so far as a temp fix.

If you do work on the manifold remove the wheel arch liner and go in that way. Makes life so much easier.

Re: Noise.....

Gearbox flex plate....

Nope - LR did not use flexplates in P38 before MY 2000 - introduced by BMW - only used on P38's with Thor engines...

The flexplate was used on GEMS vehicles, too.

Mine was already replaced 3 times....

Sorry to hijack this thread... :oops:

But I have a similar problem with the difference that I'm not getting smoke from the exhaust manifold (as a mattar of fact, this week I got the exhaust gaskets replaced). My Indy told me it's the RH head gasket. I'm not trying to freak you out, but I guess that also may be a possibility for you...

BTW, I'm not having coolant/oil leaks at the heads, which somehow puzzles me. Does anybody here thinks head gaskets are the answer ? Or am I being taken for a ride ?

My Rangie hasn't have any motor work done during it's 10 years and 101,000 miles of service. I guess it's time though, but I couldn't resisit to ask here, since the OP problem is quite similar as mine.

Thanks in advance,

N.

I told you so !!!! :)

Glad you're past that. Me, I'm still stuck with my Rangie on the shop. After the top end rebuild now I've also got a cracked exhaust manifold. :(
